SN74LV595ANS

Shift Registers Overview

The SN74LV595ANS is an 8-bit serial-in, parallel-out shift register with 3-state output registers manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and supports mixed-mode voltage operation on all ports. The device features balanced CMOS outputs capable of sinking and sourcing similar currents. It includes latching logic circuitry where the storage register state remains stable only while power is applied. The component provides partial power-down support via Ioff circuitry and includes direct clear functionality for the shift register.

Shift Registers Procurement Notes

Verify that the ordering suffix matches the specific package type required for the design, as the SN74LV595A family utilizes multiple distinct packages including NS (SO), D (SOIC), PW (TSSOP), RGY (VQFN), and BQB (WQFN). Confirm that the selected variant aligns with the thermal and physical constraints of the target PCB layout. Ensure compatibility with the system's operating temperature range and voltage levels before finalizing procurement.

Shift Registers Selection Notes

Select this component when designing systems requiring serial-to-parallel data conversion with high-speed performance in low-voltage environments. The LV series is suitable for applications needing mixed-mode voltage operation and balanced drive capabilities. Consider the specific package dimensions and thermal resistance values provided in the datasheet to ensure adequate heat dissipation and fit within the available board space constraints.

Shift Registers Part Context

This component belongs to the SN74LV595A family of 8-bit shift registers produced by Texas Instruments. The family is characterized by its ability to operate across a wide voltage range and support cascading through serial outputs. The device integrates both a shift register and a storage register, allowing for independent clocking of data shifting and storage operations.

Shift Registers Replacement Considerations

Direct substitutes include other SN74LV595A variants with different package suffixes such as SN74LV595AD, SN74LV595APW, or SN74LV595ARGY.
